To "fl whom it muy; effacer/i:

e it known that I, .lossen Mozvro, a citizen ot the United States. and a resident ol" (.leveland. in the county oVCuyahoga and State of Ohio. have invented a new and useful ln'iprovement in (lalvanizing Apparatus, of which the following is a specilication. i y

This invention-relates to the art of coating metals,as for instance.-'galvanizing.

Many 'features of my'present invent-ion are applicahle to coating metals in general, regardless of the character or conformation thereof, although, in the aecon'ipanying drawings. the invention is shown as embodied in an apparatus more especially adapted to galvanizing or otherwise coating openrndcil receptacles formed oi sheet metal. meh, for instance, as pails. An object ol"this invention is to regulate the depth or thickness of the coating applied and., preferahly. without n'iateiially chang ing or modifying the speed of the coating process; and. also, to provide means .rherehy all of 'the articles to he coated may receive a practically uniform and preiietermined depth of the coating to he applied.thereto.

Another object is to provide for the rcmoval of`the mattei' usually lloating on the surface of -the molten hath at the point where and just before the articles being coated are withdrawn from the hath.

A yfurther object is to provide mears to;` more rapidly chilling the articles they are withdrawn from thc hath in order that delivered to the withdrawing cradle which i raises them to a position where they'are each grasped hy the gripping fingers on the wit-l;- drawing arm which latter carries and delivers them onto a suitahlo support from which they,:,1re later removed hy the attendant. During the operation of th?. withdraw ing arms. and while the .articles *.arc engaged and held thereby, the means for directing Specification of `Letters Patent.

lSimilar parts are designated hy similar tot Ileference characters throughoutthe several figures of the drawings.

' Referring to the drawings. In practicing my in\Y ention the articles bte be galvanized are placed by hand in a suitable carrier or ronreyer which may be actuated, preferalf;v by means of suitable mechanism hereina'lter described. on horizontal tracks A1 to and from a position directly over the vat P containing the galianizing bath. The pails or like article. to be galvanized are forced from the carrier A by reciprocating n'ienihers C into a vertically reciprocating cradle D upon the lateral support-ing arms (l and lieneath depressing-arms tl carried in the uprights d thereof which arc secured to and extend downwardly from the horizontal member d4.

'l`l1e members and cradle D are actuated lr.' mechanism hereinafter described, Copcratirel)v with each other and the carriage A in .such a manner that'. when the carriage A with thi` articles to be galvanized thereon is brought. to a position directly over the galianiziinf bath ld. the carriage remains in this position with the articles to be galvanr/,ed in registration with the members C and cradle D while such members C are mo\;ed transversely across and above the bottbm ol` the carriage A to force the therefrom upon the lowersupporting arms 1] oi the cradle D.

Immediately after the pails are deposited in the cradle D, ,the members C are withdrawn to the left and held in their initialV positions out of the path of the carriage A which is then returned to its initial position to receive additional pails while the cradle D, previously held in its uppermost position for the reception of the pails from the carriage. is forcedV dow-'nwardly carrying the pails withvit into the galvanizing:` bath in the Yat B. the arms (l1 serving to engage the upper sides of the pails to vforce them. against their own buoyancya into the galvanizing bath.

The distance between the arms d and di of the era'dle D is'vjust sull'icient to receive between them the pails and the 'upper arms dare curved upwardly from their junctions with the upright portions of the cradle so as to allo1 the pails to readily ride out i rom thereunder by their own initial buoyancy` resulting somewhatfrom the angle of their immersion relative to the surface of the hath when `first depressed. The submerged pails then gradually settle or gravitate, to substantially the positions shown in dotted lines, upon a lower and underlying grid or support lconsisting of the series of bars E comprising horizontally eX- tending portions of the inclined bars FB onto and along which, in the first place. the pails are forced by the upper arms d1 ofthe cradle so as to free said pails from the path of the lower arms d of the cradle when th: same is 'moved upwardly for the reception of additional ails.

The bars are formed integrally with the bars El and comprise continuations thereof, and the bars El are securedat their upper right hand ends, as-seen in Fig. 4, to the right hand side wall of the open Aframe Ef which. in turn, is supported at the right by a flange e resting on the top of the right hand end wall of the vat B, and, at the left, as seen in F 4 and 5, by lugs el, carried by the frame member EL', which rest upon brackets or hooks e2, supported from the side walls of the rat B near its center. vThis frame work E2 is open, that is, without a bottom in order that an unobstructed path therethrough may be provided for the pails in their downward course as carried by the cradle D. This frame E2 is to contain the liquid (lux which. beingr lighter than the liquid metal beneath, floats .upon the sura :e thereof. The dotted lines e3 and e* in Fig.

I show approximately the levels of the upper surface of the iux in the frame E2 and of the Ualvanizing bath in the vat B. l

Oii account of che buoyancy of the pails as they'enter the bath, there is very little pressure exerted upon the inclined portions El of' the bars E and again, on account of the fact that the pails, even if made of Very heaivy stock, weigh but little in thebath'and on account of the furthe-r fact that the bars E and E1 wei li but little whe." in the bath, such bars nee to be supported only at their right handends and, being formed of angle iron, they are sufficiently rigid to retain their shape and remain 'in place when secured, as shown, by bolts or rivets to the right hand side wall of the flux carrying frame as above noted.

The pails, after they hare settled on the supporting bars ll within the bath, are nuned through the bath. in the direction of their open ends. alongr and on said bars E by a horizontally and vertically movable cradle supported l, and between two side bars R which have centrally disposed horizontal portions and upwardly and out-l wardly inclined portions at the. ends of the horizontal portions. The horizontal portions ot the hars R normally lie somewhat below the bars l". and. sui'iported on straps r extending between them. there are seen shortbars 'rm provided with upwardly pro- .iecting Fingers r arranged in two series,

spaced a distance apart somewhat greater than the length ofthe pails. and disposed at opposite ends thereof when such palls-rest upon the bars ll at the bases of the inclined portions El. 1

The cradle. comprising the bars R and parts carried thereby, is actuated` by mecha- Y nism hereinafter described. both vertically and horizontally. The vertical movement brings the right hand lingers 7j, engaging between the bars li; of each pair, into engagement with the closed ends of the pails so that, when the frame or cradle carried by the bars F is moved to the left, horizontally, a distance eorrespmiding substantially to the distance between the two series ol lingers 1', the pails engaged by the fingers of the right hand series will be moved a corresponding distance to the left still resting upon the bars E. .Xt the next similar movement of the bars R. the fingers r of the left hand series will act similarly upon the' First named pails. or upon any pails which have been previously advanced upon the supporting bars E by the right hand series of fingers 1", and deposit them into a vertically movable cage T; and at the sarne time, the right hand lingers r will advance the second or succeeding series of pails to the position from which the rst series has just been moved. (lf these fingers r. there are provided for eachpail to be engaged thereby, three in the left hand series and three in the righthand series. The center ones for engaging each pail. as seen in Fig. l). are arranged to engage between the corresponding bars E. while finger on either side of such central one engages outside of such corresponding bars E and also outside 01" the path of the bars fl of the cradle D. This is inv order that some one or moi of the three fingers r for each pail may he certain t0 engage and properly advance the pail at its right hand or closed end. The pails are thus moved step by step through the. bath from right to left. being delivered thercinto by the cradle D at one end and withdrawuat the other end by the cage ol which the bars T comprise the bottom. This rage is reciprocated vertically. by mechanism hereinafter described. and so timed in its action that the bars comprising its bottoni are disposed in a plane beneath. the supporting bars E, while the bars R carry ing the tigers r are feeding the pails thereto.

After each series of pails is deposited upon the vertically' reciprocating bars T. the latter are elevated while the bars R are bcing returned to receive another series of poils. \Vhen the pails are elevated by the bars1 T to a predetermined position. the upper edge of the open end of each pail is caught beween a pair of suitable gripping jaws h and L. lnounted on the outer ends of arms H secured upon a rock shait s. and are thereby lifted out of the bath and depositerl right side up upon an exterior support li. as best shown in Fig. 4. whereupon the gripping jaws are released and "returned lo their starting positions ready to receive arrrlher pail or series of pails.

flaring the 'forward operation ol' the arms li. aan', while the mils are. held by a re.

the gripping jaws carried thereby, the pails are exposed to a strong current of air for the purpoal of monl rapidly chilling them, the construction and operation of the means l'or cller'ting which will be more fully plained later.

The gripping iawf la and /i and their arms lgi are actuated by suitable mechanism synchronized in their operation with those prm'iouslj.y referred to.v and they may be actuated from the same source. as

a cone pnlley d, which in turn may be connected by a belt to any available. source. of power, not shown. Thi.` pulley .l is secured upon a suitable shaft j revoluhlr suiiiported., in suit-- able bearings. and having thereon a pinion /f meshing with a gear K on a shaft M. journaled 'in suitable bearing. ym upon a main supporting Vframe N, for transmitting power tn the sei-eral mechanisms previousli` referred to.

The tracks .V for the carriage may preferably be channel irons properly spa-Sed apart to revolve rollers o on the upper portion of the carriage frame and extend some distance beybnd the vertical plane of the vat l5 and toward the operator, as seen in Fig. l. ilountcd upon the extreme opposite ends; ol they track A1 are bearings f1 in which journaled shafts carrying uitahle sproclwts or drums u2 connected by a eh, n .W and haviag its ends attached to the ends of the carriage A. i en in Fi f' and i.

A pinion n seemed to the. shaii ing the rear sprocket wheel fr" and with the sliding rack a", the larer hai one end slotted to receive the :a which it is guided. and also provided roller or stud which rides ir g. i cam P, as best seen in Eig. 7, sait. cani being mounted direetly on the shaft M 'to rotate therewith and thereby reciprocaw.3 the @liliing,r rack o* to rotate the sprorkete and thereby reciprocate the carriagt` A. 'The cam l" has two portions of approrimatcly equal angular extent concentric with the shaft M t.) permit the carriage to remain at rest for a sufficient period at eavn end ol' its course.

The mechanism for reciprocating the cradle D is as follows zmecured to the shaft hl is a worm gear a: meshing with a similar worin gear nl on the shaft .if which is jourY naled in 1suitable bearings m on the. main frame N and provided with crank arms d? which are connect/ed by links (lf to a cross head having attached directly thereto the vertical4 d movable vertically on suitable guides f/f". The crank arm d2, the throw of which is; sullhzient to effect the desired vert cal movement of the parts, is shown in Fig. l in position to hold such parts in thei appern'iost pmitions ready to receive the pails from the carrier A.

The members (1.' for forcing the pailsfrom i is the carriage A, are mounted upon the lc' ends of the parallel rock arms c, on: of which is provided with a toothed segment c1 mounted in a shaft s and meshing with a similar segment c2 on the stud o3, the latter .in turn mounted in the main frame N. The segment c2 has a slotted arm c4 to receive a stud ci on the horizontal sliding bar C1. This bar C1 is guided in suitable ways c and cf on the :nain frame N and is provided with a lengthwise slot c1 for receiving a transverse shaft s1. Mounted upon this bar C1 is a rolleror stud' 08 which rides in a grooved cam P1 mounted upon and rotated with a shaft a1 to engage said roller and thereby reciprocate the bar c1 which,rin turn, causes a rocking motion of the segments c1 and c respectively, for reciprocating the members C.

The cradle carried by the bars R is actuated vertically by opposite sets of bell crank levers r1 and links r2 pivotally suspended from the lower ends of such levers and also pivotally attached to the bars R at their left hand ends and to the extensions thereof to the right of and above the vat B. These bell crank levers r1 are secured to the opposite ends of parallel `transverse rock shafts s2 and s3 and are connecled for simultaneous action by bars r3. The bell crank levers r1 are operated simultaneously by a reciprocatory sliding bar R1, which is guided in suitable ways r* on the main frame NL, and is 0perated by the crank arm r on the shaft s2. 'lhis sliding bar R1 is moved back and forth by a suitable cam P2 engaging a stud or roller on the bar R1.

l'lorizontal rocking motion is imparted lo the bars R1 by means of a rock shaft s* having crank arms 7"" and r1 thereon, the arms r being located at opposite ends of the shalt. .fs-1 and adjustably connected at their louer ends to the arms R, as seen in Figs. 1 and 4. The arm fr? is pivotally connected to a bar R2 which is guided to reciprocate horizontally in suitable ways on the main frame N and is actuated by a grooved cam or concentric P. as seen in Figs. 1 and 4.

Both of the cams P2 and P3 are mounted upon the same transverse rotary Shaift s which is journaled upon the main frame N and is provided with a ivorm gear v3 mesh! initr with a similar worm gear nl on the main shaft M, thereby ii'nparting continuous rotary motion to both of the cams l2 and Pa b v 'which the levers r1 and f/'T are operated to vertically and horizontally reciprocate the. bars "l,

Guide rods t5 are secured in the main frame N to constitute vertical guides for and upon vvhich the members U1 and U2 vertically re ciprocate to properly control the movements of the bars T. A grooved cam lN is mounted upon and rotates with the shaft 81 and engages a roller or stud upon the outer end of the lever formed on or carried by the curved shaft T2 working in bearings t and provided at its ends beyond the bearings with arms t each having an extension t1 connected by links t2 to one of the mein-f bers U. The extensions t1 are adjustable,l lengthwise of the arms t for varying the amount of the movement of the member U through the medium of pinions t3 meshing with toothed racks on the extensions t1, said pinions being secured upon a common shaft and adapted to be rotated by hand to effect the desired adjustment, after which the eX- tensions are each held in adjusted position by a clamping screw The cams P1 and P1 are mounted upon the transverse shaft 81 driven from the main shaft M by intermeshing ears t and r", having their teeth dispose( at an angle of 45o and substantially the same as the gears c and u1 and r2 and 'r2 for transmitting rotary motion from the main driving shaft M to the shafts s and s* resi'iectively.

I will now describe the meansfor actuating the rocking arms H, best seen in Figs. 1. Q, B, 4 and t. The bars O are. caused to reciprocate vertically in the guides (11 b v means of the grooved cam P on the shaft M engaging a roller o on the cross bar (Y)2 connecting the arms O. 'footbed racks 01 are arranged to reciprocatein the guides 01 parallel with the bars O and are pivot ally connected to the bars O b v means of the links 01 andv o?. The link o1, near the ob server in Fig. 4, has an arm O. constituting such link a bell crank lever, and this arm has therein a slot extending lengthwise of the arm to receive an adjustable roller or pin 03 which engages in the cam slot oi in the plate V. The plate V is adjustable vertically on the plate V1. which in turn is adjustable obliquely on the plate V2, vfhich is supported upon a bracket. V3 mourted on the frame N of the machine. The toothed racks O3 mesh with pinions or toothed seg ments o on the shaft s to which the arms H are secured. The shaft s is mounted in bearings formed in the brackets m8 secured to the upright end members of the frame N of the machine. The cam P5 is conformed so as to cause each arm to be swung through practically three. quarters of a revolution that is. from the horizontal position in which it receives the pail to the vertical position in which it discharges the pail, as seen in Fig. 4. It will be seen that, by means of the above construction, the racks (`)E will be reciprocated with the bars O and at the same rate of trvel until the. roller engiigls the cnm in the slot 0 in the plate V whereupon the consequent throw ofthe z lever o causes the racks to travel slower 5 than the bars O until the crestof the. ouin is :ind thereafter correspondingli" .reiiehed f :isterLf B v adjustingy the roller o in the sliot in the leifer o, the amount of suchv retgirdze tion is Achanged.
